10.1.5 Parameters in Command

Four basic parameter types: Boolean type, keyword, variate and binary
number
Boolean type: OFF|ON|0|1
The Boolean type represents a binaryzation value. 0 has is equivalent to
character string OFF. 1 or any other nonzero number are equivalent to ON.
It would return to ON or OFF when checking.
For example: BWIDth：VIDeo：AUTO ON indicates setting VBW as valid.
Keyword:

below could also be used in some commands. But not all commands support
them:
UP – increase parameter value
DOWN – decrease parameter value

the variate type (describing below). If there is no unit, the system would

number.
